Fucus serratus on sheltered lower eulittoral rock

Sheltered to extremely sheltered lower eulittoral rock with Fucus serratus (for detailed description of the rich associated community please see unit MA1-23F1). Two variants of this biotope have been described((( - Fully marine conditions (MA1-23F1) and mixed substrata (MA1-23F2). Please notice that three other biotopes with a F. serratus dominance have been described: Variable salinity (MA1-256), tide-swept (MA1-239) and tide-swept on mixed substrata (MA1-23A).$$$Situation: This biotope usually occurs immediately below a dense canopy of Fucus vesiculosus (MA1-23D) on sheltered shores or an Ascophyllum nodosum zone (MA1-23E1) on sheltered shores((( consequently low densities of these species may occur in this biotope. The sublittoral fringe below is dominated by the kelps Laminaria saccharina and Laminaria digitata on sheltered shores (MB1-23A1((( MB1-2391).
